Traits in RUST

 Traits in RUST

Traits define behavior that a type can implement. They are similar to interfaces in other languages. Here's an example:

rust

trait Printable {

    fn print(&self);

}

struct Rectangle {

    width: u32,

    height: u32,

}

impl Printable for Rectangle {

    fn print(&self) {

        println!("Rectangle: {} x {}", self.width, self.height);

    }

}

fn main() {

    let rect = Rectangle { width: 10, height: 20 };

    rect.print(); // prints "Rectangle: 10 x 20"

}
